Oh come on, people. You are cruel and unfair to poor BFL. It's not like they are not trying But seriously, 600mhash/s how are they going to cool all that in such small blade? Will it be again "two more weeks and you have it in your hands, we swear! We just need to fix cooling/power issue it will take 3 more days and you'll have it in 2 weeks!"

If it only consumes 350W due to the new smaller technology, then it´s like a graphicsCard´s power throughput. Therewith theoretically possible. But remember what they´ve said about Jalapeno´s power consumption: originally 4,5W, later corrected to 30W. If same with this new blade, you will get something like 2kW... then there is a big problem. I won´t buy it, I´m still waiting for my Single. I don´t want to buy new hardware for mining endlessly.

I bet, short time before they deliver, they will announce the new "Empire Blade" with 5TH, Preorders now, customers of "Monarch Blade" can be switched by a fee of 15%. Alleged "Delivery late autumn 2014"...

One thing is clear: They are the real winners. I´m not against technical progression, but I´m also not it´s junky.

If they deliver by end of year, that 600 GH/s unit will only mine 1.1 BTC/day

If Bitcoin difficulty continues to rise at the current rate then one of these units will mine a little more than 2BTC in the whole of January next year. The 'mine it forever' total being around 4 BTC. Then you have to pay for electricity.

That is based on the 35% rise seen last cycle multiplied every ten days taking difficulty to a little over 3 billion by the start of 2014 and then just plugging that value into a bitcoin profitability calculator.

OK, perhaps difficulty will not increase at that rate but then 'perhaps' BFL will not deliver on time and the difficulty may be even higher by the time that they start to ship these units to customers.

a lot of stupid ppl will preorder it.. so as long as people are willing to be ripped off we will always have some scammers around

The best estimate to date, for the past four days, BFL added just under six million dollars to their coffer sans ANY formal announcement. But heck, they earned it, for shopping a GPU blade is hard. They almost didn't meet the Saturday morning deadline. Luckily, Nasser, the Persian in France, stayed up late and answered all he wanted to answer, avoiding the important questions, in perfect English.

So you have to wait for 1000 USD per BTC to make ROI, not bad.But January seems soo optimistic given their track record

Who is Nasser? What's this all about? And where did you hear this?

Please don't take my reply as dissing you, but... Seriously, if you don't know who Nasser is or have the knowhow to Google [Nasser Bitcoin], you are in a load of shit if you are a BFL customer or are planning on becoming one without doing one iota of due diligence. Do you even know who Sonny Vleisides is?
